Note: The following is my headcanon and my version of how I see my humanized versions of the MLP characters and does not affect the show itself. If you don’t like them then oh well.
 
Tara Gordon is an Afro Canadian, her family enjoyed a very upper middle class lifestyle, with her brother being a high ranking officer in the Canadian Army. Being far too different from her peers, where they listened to rap and pop music, she listened to classical, instead of going out, she stayed home and read books. She was always into science always trying to find answers to the unknown and trying to solve everything that could was unsolvable. Her only friends were her older brother, John and her adoptive brother, Leroy. Not knowing how to make friends, she seemed cold and didn’t want to do anything with anyone, However when she meets her new friends she begins to warm up and is given the Element of Magic by Celestia which gives her the power of the mystic arts. As a science major she cannot believe at first, but soon accepts her powers and her new friends as well. Twilight is very skilled in the mystic arts. She tends to carry around a spell book to help her chant spells when in battle. Tara can also use Astral Projection when necessary and can travel through different realms. She serves as the leader of the group, always using strategies in order to help her friends.
